UNITED STATES PATENT ornce TRIPHENYLMETHYL BUTYL ETHER AS AN IN SECTICIDE Ingenuln Hechenbleikne signer to Ameri r, Stamford, Conn., ascan Cyanamid Company, New
York, N. Y., a corporation of Maine No Drawing. Original application May 31, 1940, Serial No. 338,047. Divided and this application October 23, 1944, Serial No. 560,028. In
Canada April 9, 1941 5 Claims. (01. 16'l-30) Example parts of triphenylmethyl chloride were added to a solution consisting of 0.83 part of metallic sodium dissolved in 10 parts of butyl alcohol. The mixture was heated upon a steam bath for one hour, then poured into water and extracted with ether. The ether extract was washed with a large volume of water and dried over sodium sulfate. The triphenylmethyl butyl ether crystallized after evaporation of the ether. After recrystallization from ethyl alcohol the product had a melting point of 50 0.
Spray solutions were prepared by dissolving the triphenylmethyl butyl ether in a solvent medium consisting of 65% acetone and 35%v water; A
100% control was obtained when a spray of 1-1000 dilution was used against the citrus red spider and 0 its eggs. The insecticide also gave a 99.5% control on the citrus red spider with a spray of 1-2000 dilution.
Triphenylmethyl butyl ether, while especially eilective for controlling the red spider and its eggs, may also be used for the control 01. aphids, white fly nymphs, garden fleahoppers and the like. This new insecticide may be applied in any of the conventional manners. Thus, for example, it may be used as an aqueous solution, in an aqueous emulsion or it may also be incorporated in organic liquids such as the aliphatic and aromatic hydrocarbons for spraying purposes. It may be effectively used in dusts with solid diluents such as kieselguhr, wood flour, walnut shell and talc.
5 This'application is a division of my copending application Serial No. 338,047, filed May'31, 1940,
now Patent No. 2,411,428.
While the invention has been described with particular reference to specific embodiments, it
.1 is to be understood that it is not to be limited thereto butis to be construed broadly and restricted solely by the scope of the appended claims. a
I claim: 1. A method of combating insect pests which includes exposing them to a. toxic quantity of triphenylmethyl butyl ether.
2. An insecticidal composition including a toxic amount of triphenylmethyl butyl ther and a distender. 7
3. An insecticidal composition including a toxic amount of triphenylmethyl butyl ether incorporated in an aqueous emulsion.
4. An insecticidal composition including a toxic amount of triphenylmethyl butyl ether incorporated inan organic liquid solvent.
5. An insecticidal composition including a toxic amount of triphenylmethyl butyl ether incorporated in a solvent medium consisting of 65% acetone and 35% water.
